2. Frederic Fekkai Hairspray

"This hairspray ($39; fekkai.com) is my favorite product of all time," says Adir Abergel, who spritzed it on Dianna Agron's strands to keep her fishtail updo in place. "It has incredible hold and memory, but doesn't leave hair stiff, which is important since I change styles all the time on set."

4. Healthy Sexy Hair Leave-In

"If this leave-in conditioner ($10; drugstore.com) ever gets discontinued, I'll have to quit doing hair!" says hairstylist Kristin Ess, who uses the product on Lauren Conrad. "The product completely changes hair in just a few pumps by creating perfect, weightless shine and restores the pH balance. Plus, it just smells epic."
